The day-to-day reliability of peak fat oxidation and FAT_MAX.

ABSTRACT:

Purpose

Prior studies exploring the reliability of peak fat oxidation (PFO) and the intensity that elicits PFO (FAT_MAX) are often limited by small samples. This study characterised the reliability of PFO and FAT_MAX in a large cohort of healthy men and women.

Methods

Ninety-nine adults [49 women; age: 35 (11) years; [Formula: see text]O₂peak: 42.2 (10.3) mL·kg BM^-1·min^-1; mean (SD)] completed two identical exercise tests (7-28 days apart) to determine PFO (g·min^-1) and FAT_MAX (%[Formula: see text]O₂peak) by indirect calorimetry. Systematic bias and the absolute and relative reliability of PFO and FAT_MAX were explored in the whole sample and sub-categories of: cardiorespiratory f
